I noticed now that my version of WordPress (3.5.1) is not supported. I do not have any custom plugin for login page but I use the auctionpress template at http://www.alltinget.com. Looking into another plugin right now that fit my version and seems to work but thanks anyway and for fast respons!
Hello! I have exactly the same problem as above. Only shows up in registration page and not login page. When I click the FB button i end up on the login page and no FB login is presented.
